The Long Lake oil sands upgrader project is an in situ oil extraction project southeast of Fort McMurray in the Athabasca oil sands region of Alberta. The project is operated by Nexen, a wholly owned subsidiary of China National Offshore Oil Corporation (CNOOC) Limited. Long Lake is an integrated steam-assisted gravity drainage (SAGD) and upgrading operation that uses a proprietary OrCrude technology as well as hydrocracking and gasification to produce Premium Synthetic Crude (PSC) oil. Production capacity at Long Lake is of bitumen which, when upgraded, generates approximately of crude oil. ==History== In 2001, Nexen formed a joint venture with OPTI Canada Inc. (OPTI) to develop the Long Lake lease using SAGD for in-situ bitumen production and OrCrude technology to upgrade the bitumen to PSC. The first phase of the project received regulatory approval in 2003 and was sanctioned in 2004. Construction at the site began in 2004. Steam injection began in 2007 and the first production was in 2008. SAGD bitumen operations at Long Lake started in mid-2008 and production of PSC from the upgrader began in 2009. Early in 2009, Nexen acquired an additional 15% interest in the Long Lake project, increasing the company’s ownership level to 65%. Following this acquisition, Nexen became responsible for operating the entire project. There have been some technical problems and the project has failed to meet production projections. As of early 2011, the site was producing about and OPTI was struggling under a heavy debt load and lack of liquidity. On February 1, 2011, OPTI appointed Lazard Freres & Co., a bankruptcy specialist, raising speculation that restructuring or bankruptcy for the company was imminent. In 2011, CNOOC Limited acquired OPTI, which included the 35% non-operated interest in the Long Lake project and joint venture lands. On February 25, 2013, Nexen was acquired by CNOOC Limited.〔(CNOOC Limited Completes Acquisition of Nexen Inc. )〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Long Lake (oil sands)」の詳細全文を読む スポンサード リンク
